I suffered from headaches for 4 to 5 years before I started seeing Dr. Donahue.  This was my first chiropractic experience and was lucky enough to have Dr. Donahue explain how I could actually be headache free. At first I was totally skeptical but decided to keep an open mind because nothing else was working .  To my amazement and utter shock, after only 3 visits with Dr. Brennan I am headache free. Dr. Donahue was confident that he could help and was just as shocked at how quickly my headaches went away.  Thank you Dr. Donahue for truly helping me live headache free!
